Although the US drone attacks have been a source of tension between Washington and Kabul, US-led foreign forces have recently expanded the strikes across the country.

Washington claims the targets of the drone attacks are militants, but local officials and witnesses maintain that civilians have been the main victims of such raids over the past few years.

Afghanistan was invaded by the United States and its allies in 2001 as part of the so-called war on terror. Although the Taliban was removed from power as a result of the offensive, insecurity remains across the country.
